Which of the following statements accurately describes what we learned about HIV evolution?
| a. |
HIV is more deadly in Northern Europe, but more transmissible in Africa. That is why there are more individuals infected with the illness in Africa. |
|
| b. |
HIV shares a most recently common ancestor with Simian Immunodeficiency Virus (SIV) such that SIV evolved as it host-switched from chimpanzees and gorillas into humans multiple times. |
|
| c. |
Drug development is exceedingly difficult because there are very few drug targets for HIV and AZT (a reverse transcriptase inhibitor) alone is the single most effective treatment for HIV. |
|
| d. |
Evolution of HIV virions within a person is quite slow such that a blood draw after 1 year of infection would reveal that every single virion would have the exact same sequence. |
Human immunodeficiency virus is a deadly virus that attacks the helper T cells of the cell mediated immunity as a result the immune cells are destroyed and a simple disease can overtake and could be the cause of persistent illness or death.
